1. A nurse is caring for a client who came to the emergency department reporting chest pain. The provider suspects a myocardial infarction. While waiting for the laboratory to report the client's troponin levels, the client asks what this blood test will show. The nurse should explain that troponin is

Correct answer: C

Rationale: The correct answer is that troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. Troponin is a specific marker for heart muscle damage, particularly seen in conditions like myocardial infarction. Choice A is incorrect as troponin is not an enzyme that indicates damage to brain and skeletal muscle tissues. Choice B is incorrect as troponin is not a protein whose levels reflect the risk for coronary artery disease; it indicates heart muscle damage. Choice D is incorrect as troponin is not a protein that helps transport oxygen throughout the body; its presence in the bloodstream is specific to heart muscle damage.

2. A client is receiving oxygen therapy via a nasal cannula. The nurse should explain that this method of oxygen delivery does which of the following?

Correct answer: A

Rationale: A nasal cannula is a device used for delivering supplemental oxygen to patients. It delivers a specific concentration of oxygen constantly, typically ranging from 1-6 liters per minute. This method is effective for patients who require low to moderate levels of oxygen. Choices B and C are incorrect because a nasal cannula does not deliver a high concentration of oxygen and is not considered a low concentration delivery method. Choice D is incorrect because a nasal cannula does not restrict the client's ability to eat, speak, or drink; it allows them to perform these activities while receiving oxygen therapy.

3. A nurse in a clinic is caring for a client who came to be tested for tuberculosis (TB) after a close family member tested positive. The nurse should know that which of the following is a diagnostic tool used to screen for TB?

Correct answer: B

Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

4. A client prescribed home oxygen therapy is receiving discharge teaching from a nurse. Which statement by the client indicates a need for further teaching?

Correct answer: A

Rationale: The correct answer is A. The client's statement indicates a need for further teaching because the flowmeter indicates the flow rate of oxygen, not the total amount of oxygen being delivered. Choices B, C, and D demonstrate understanding of safety measures and indications for seeking medical attention in relation to home oxygen therapy, making them appropriate statements.

5. A client comes to the emergency department reporting chest pain that is sharp, knife-like, and localized to an area he points to with one finger. The nurse should document this chest pain as which of the following?

Correct answer: D

Rationale: The correct answer is 'Pleuritic pain.' Pleuritic pain is characterized by sharp, knife-like pain that worsens with deep breathing or coughing and is localized to a specific area. This type of pain is often associated with inflammation of the pleura. Choices A, B, and C are incorrect. Angina pectoris is a type of chest pain caused by reduced blood flow to the heart muscle. Cardiogenic pain refers to pain originating from the heart itself. Myocardial infarction is the medical term for a heart attack.
